HERBERT FLANDERS,` OF MANCHESTER, NEW HAMPSHIRE.

'sAsH-HOLDER.

SBECIFICATION forming part 0f Letters Patent N0. 714,569, dated November 25, 1902.

Application led November SO, 1901. Serial No. 84,202. (N0 mOdel-l To `cir/ZZ whom zit may concern.-

Be it known that I, HERBERT FLANDERS, a citizen of the United States, residing at Manchester, in the county of Hillsboro and State of New Hampshire, have invented an Improvement in Sash-Holders, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention has for its object the production of a novel fastener to retain a partially-lifted sash in any desired position to thereby regulate the size of the space through which air may pass.

Figure 1 in elevation shows a sash-frame and sash embodying my invention, and Fig. 2 is an inner side View of the holder detached and part of the rack-bar with which it coacts.

The sash-frame or window-casing A and the upper and lower sashes B C are and may be all as usual, the edges of each sash entering and sliding in usual grooves in the sashframe or casing.

I apply to the sash-frame or casing at Vone or it may be at both sides thereof a suitable toothed rack D. One of my novel holders E is shown as applied to the right-hand side of the lower sash; but in practice I may apply a like holder to the left-hand side thereof.

The holder E comprises a shell e, provided with ears e', having holes for the reception of screws and cast to present a projection e2 The shell sustains a stud e4, on which is mounted a lever e5, havi ing at one end a stud e6. The opposite end of said lever has a curved flange e7, from which is extended a handle e8. The stud ei receives on it a toothed Wheel o, that engages the teeth of the rack D. The lever e5 has a stud 2, on which is pivoted a detent-pawl cd, that normally rests by its L free end against the periphery of the toothed wheel d and permits said wheel to be rotated on theL stud e6 only in thedirection of the arrow thereon, (see Fig. 2,) as when the window-sash is being lifted to open the window. A spring b, connected at one end with said lever e5 and at its other end with a stud 4 of the shell, acts normally to turn said lever and keep the toothed wheel pressed toward and so that the teeth of said wheel mesh with the teeth of the rack D.

If one lifts the sash by engaging a sash-lift c, the wheel of the holder will be rotated freely by its engagement with the rack; but instantly after removing the force used to overcome the weight of the sash the slightest descent of the sash causes the end of the lever e5 carrying the roller to rise until the back of the detent ot meets the stud 4, and as the roller then sustaining the weight of the sash is restrained from rotation by the detent in a direction opposite the arrow, Fig. 2, it follows that the sash may be left open at any point, that depending upon the quantity of air-space desired.

To lower the sash, `one will engage the end e8 of the lever and turn it about the stud e4 far enough to disengage the teeth of the wheel from the teeth of the rack, and thereafter the sash is free to descend.

With this holder the sash is always in condition to be raised; but it cannot be lowered except by moving the lever by the fingerpiece e8.

The holder is very desirable for use in cars and preferably two holders will be applied to each sash, and, if desired, the sash may be lifted by engaging directly and lifting on the ends e8 of the levers. The wall e7 substantially closes the gap in the side wall of the shell, thus adding to the neat appearance of the holder.

Having .described my invention, what I claim as new, and desire to secure by Letters Patent, is

-1. .In a sash-holder, a shell havinga chamber and adapted to be secured to a sash, alever pivoted on said shell andhaving at one end` a thumb-piece and sustaining at its opposite end a toothed wheel, a detent to` prevent the rotation of said wheel in one direction as when sustaining the weight of a sash.

2. In a sash-holder, a shell having a charnber and adapted to be secured to a sash, alever pivoted on said shell and having at one end a thumb-piece and sustaining at its opposite end a toothed wheel, a detent to prevent the rotation of said wheel in one direc- IOO tion as when sustaining the Weight of a sash, and a spring actingnormally to elevate the end of said lever carrying said toothed Wheel.

3. In a sash-holder, a shell having a chamber and adapted to be secured toa sash, alever pivoted on said shell and having at one end a thumb-piece and sustaining at its op-` posite end a toothed-wheeL'a detent to prevent the rotation of said wheel in one direction, as when sustaining the Weight of a sash,

a spring acting normally to elevate the end of said lever carrying said toothed Wheel, andY means against which the detent is forced when the Wheel and lever sustain the weight of a sash to thereby hold the detent firmly in x 5 engagement with said wheel to prevent it .from being rotated by the Weight of the sash.
